'Orthodox' means orthodox in life as well as faith

"Orthodoxy isn’t up for negotiation, and it isn’t subject to member surveys. Nor is it cleanly detachable from moral and social questions. The one clear case of excommunication we have from Paul’s letters involves a man who was sleeping with his stepmother. Sexual ethics, like other moral matters, is part of the Church’s witness and has been from the beginning."
